Green Safety Guard Day

What Is Green Safety Guard Day?

Every November 19th is "Green Safety Guard Day" (緑のおばさんの日, Midori no Obāsan no Hi) in Japan. On November 19, 1959, Tokyo Metropolitan Government established the "Gakudō Yōgo-in" (学童擁護員, "Child Safety Guard") system — deploying uniformed adults at school crossings to ensure children's safe passage. These safety guards — most frequently women wearing green-yellow uniforms and carrying orange flags — became known affectionately as "Midori no Obāsan" (緑のおばさん, "Green Aunties"), a term of warm familiarity that reflects their beloved place in Japanese school community life.

The Green Aunties in Japanese Life

The "Midori no Obāsan" (officially Gakudō Yōgo-in) are a fixture of Japanese elementary school mornings — standing at dangerous road crossings with orange flags and stop signs, halting traffic to allow children safe passage on their walks to school. Their green-yellow jackets and white gloves, combined with their cheerful greetings and familiar faces, have made them beloved community figures. Children grow up with the same safety guards at the same corners for years, and the Midori no Obāsan become part of the neighborhood fabric of Japanese school life.

The "Walking to School" Culture

The Green Safety Guard system reflects a distinctive aspect of Japanese childhood: the expectation that children walk to school independently (or in groups) rather than being driven by parents. Japanese elementary school children typically walk to school with neighborhood groups (班, han), supervised en route by safety volunteers including the Midori no Obāsan at road crossings. This practice is credited with building children's independence, neighborhood knowledge, and social bonds — though it requires the safety infrastructure that the Green Safety Guards provide.

Community Safety Networks

The Midori no Obāsan system is part of Japan's broader community-based approach to child safety. Volunteer neighborhood patrollers, police koban officers, and designated "children's safety houses" (子ども110番の家, Kodomo 110-ban no ie) — homes and shops that have agreed to shelter children in danger — together create a dense safety network around Japanese schools. This community-based safety infrastructure reflects Japan's cultural emphasis on collective responsibility for children's welfare.

Fun Facts

• Gradual shift to volunteers: In recent decades, many Midori no Obāsan positions — which were paid municipal employees in Tokyo — have been supplemented or replaced by PTA parent volunteers, reflecting both budget pressures and the desire to maintain the community character of the role.
• Children's safety houses: Japan's "children's safety house" (子ども110番の家) network — shops, homes, and businesses displaying a yellow sign indicating they will shelter a child in danger or distress — creates a distributed safety net across Japanese neighborhoods that complements the Midori no Obāsan's role at school crossings.
